One of the firefighters was treated at a local hospital and released, while two were admitted with non-life-threatening injuries to Lehigh Valley Hospital in Salisbury Township, Emergency Management Coordinator Kristopher Mattson said this morning.

The fire, which destroyed the single-story ranch-style home, was reported about 9:39 p.m.by a passerby and was under control just after midnight, Mattson said.

Northampton County Coroner Zachary Lysek has not made a formal identification. It is not immediately clear if the fire or some other factor led to the person's death.

Northampton County property records say the home was owned by James S. Cenchitz, who lives at that address, records state.

Mattson was unsure if the person was alive when found, but firefighters were not able to remove the body from the building, he said.

Firefighters initially took an offensive stance battling the blaze, but once "the building became compromised and collapsed," they had to pull back from the home, Mattson said. He couldn't say if the firefighters were injured in the collapse.

The nearest fire hydrant wasn't shoveled out, so while firefighters attended to that, water on the trucks was used, Mattson said, reminding residents to shovel around hydrants at their homes.

"It did not slow down" the effort to quell the fire, he said.

Ice buildup and very cold temperatures added challenges, he said.

The Pennsylvania State Police fire marshal and the coroner will head the ongoing investigation, he said. It was not immediately clear what started the fire or in what part of the building it began, he said.

"It's completed destroyed," he said of the home. What happens to the house will be up to the township zoning office and the resident's insurance company, he said.
